Filed: 1981-12-11
Abstract: PURPOSE:To prevent a belt mark, and to stop an original at an exposure position easily and exactly, by providing slits through an original feed belt, and allowing stoppers to move up and down through the slits to stop the original at the exposure position. CONSTITUTION:An endless belt 30 for feeding an original has parts 32 having no slit and parts 33 having a proper number of slits formed at constant intervals in the width direction. Original stoppers 71 are allowed to move up and down through the slits 33 from the inside of the belt 30. When an original held between the belt 30 and an original cover glass is fed to an exposure position, a  prescribed actuator drops down to actuate a solenoid and engage the stoppers 71 with the slits 33, and the original comes at their ends into contact with the stoppers 71 and stops at the position D, thus permitting a belt mark to have no danger to occur, the original to stop at the exposure position easily and exactly.

Filed: 1985-09-10
Abstract: PURPOSE:To surely prevent a shift in timing of the leading end of a sheet due to a slip of the sheet, by providing an intermediate roller drive means for rotating an intermediate roller at a predetermined timing. CONSTITUTION:The timing for initiating a secondary paper feed, is the timing with which an optical system starts the exposure of an original copy, and therefore, a resist roller drive section 71 actuates at first a clutch 72 to rotate a resist roller 4 for a predetermined time so that a sheet is conveyed to an exposure drum 6. Further, a conveying force by a conveyer roller 5 is applied on the way of conveyance to ensure the conveyance of the paper sheet. Further, when a predetermined time elapses from the time at which the sheet is initiated to be fed, an intermediate roller drive section 76 actuates clutches 77a, 77b to rotate intermediate rollers 3a, 3b for a predetermined time so that the sheet is conveyed leaving a slight deflection in the sheet. Thereby it is possible to surely prevent a delay in paper feed due to a slipping.

Abstract: PROBLEM TO BE SOLVED: To smoothly increase the output by fully opening a main exhaust port at a first prescribed revolving speed of a two-cycle engine having main and auxiliary exhaust passages, and fully opening auxiliary exhaust ports at a second prescribed revolving speed higher than the first revolving speed. SOLUTION: During the low-revolution operation of an engine, auxiliary exhaust valves 18A, 18B are rotated and closed via a rack and a pinion interlocked with a drive source such as a governor.

Filed: 1988-08-15
Abstract: PURPOSE:To perform the work for cleaning and passage test in one work stage and to improve workability by running an mobile device in conduit line through a cable tow rope containing feeders. CONSTITUTION:As an arm 14 having a roller 12 for in-conduit line mobile devices 20a, 20b and 20c comes into contact with the upper inner wall of an underground conduit line 8, wheels 11 are pressed to the travelling inner wall to increase frictional force, so that towing force is enhanced to the specified strength. With a control device 5 or a remote controller 6 the current is fed to mobile devices 20a to 20c in conduit line through a drum rotation section 1 and a cable tow rope 2 containing feeders. By the control operation of the control device 3 or the remote controller 4, as the drum rotation section 1 rotates, the mobile devices 20a to 20c travel along inside the underground conduit line 8. The pulling-in of the cable tow rope 2 into the underground conduit 8, the cleaning and the passage test inside the underground pipe 8 are performed simultaneously. Consequently, as the repetition work depending on human power is automatically performed in one work stage, the workability is improved.
